Overview of the Meike 85mm F1.8 SE Mark II STM and YONGNUO YN50mm F1.8

The Meike 85mm F1.8 SE Mark II STM is positioned as a high-resolution portrait lens compatible with Sony E Mount cameras, whereas the YONGNUO YN50mm F1.8 is a versatile lens designed for Canon EF Mount cameras. Each lens offers unique features tailored to specific photography styles and camera systems. The Meike lens is priced at $229.99, while the YONGNUO lens is significantly cheaper at $82.00, making it about 64% less expensive.

Design and Build Quality

In terms of design, the Meike 85mm F1.8 SE Mark II STM emphasizes a compact and lightweight construction while integrating advanced optical elements. Its multi-coated lens elements help reduce flare and ghosting, which is crucial for achieving high-quality images. On the other hand, the YONGNUO YN50mm F1.8 features a standard lens structure with 5 groups and 6 slices, which is adequate for general photography. However, it lacks the advanced coatings found in the Meike lens, which could impact image quality under challenging lighting conditions.

Aperture and Bokeh Quality

The Meike lens boasts a wide f/1.8 aperture with 11 diaphragm blades, designed to produce beautiful bokeh effects that are particularly appealing for portrait photography. In comparison, the YONGNUO lens also features a large f/1.8 aperture but has a simpler lens structure. While both lenses can create a shallow depth of field, the Meike’s design is likely to yield a more aesthetically pleasing bokeh due to its higher blade count. This makes the Meike lens better suited for portraiture and artistic photography.

Focusing Performance

Focusing is another critical area where these lenses differ. The Meike 85mm F1.8 SE Mark II STM is equipped with a stepping motor (STM) that provides silent and smooth autofocus, enhancing the shooting experience, especially in quiet environments. In contrast, the YONGNUO YN50mm F1.8 offers both auto and manual focus modes, which gives users more control but may not be as fast or quiet as the Meike’s STM technology. This difference in focusing mechanisms can significantly affect usability for different photography styles.

Compatibility and Versatility

The Meike lens is designed explicitly for Sony E Mount cameras, including the A7 series, making it highly specialized for users of that system. Meanwhile, the YONGNUO lens is compatible with both full-frame and APS-C format Canon EF cameras, increasing its versatility. It supports various camera shooting modes and displays aperture data in the EXIF information, which can be beneficial for Canon users exploring different shooting scenarios.

Price Comparison

The price difference between these two lenses is notable. The Meike 85mm F1.8 SE Mark II STM retails for $229.99, while the YONGNUO YN50mm F1.8 is priced at $82.00. This represents a staggering 64% savings for those opting for the YONGNUO lens, making it a more accessible choice for hobbyists or those on a budget. The substantial price gap may influence buyers who are looking for a cost-effective option without needing the specialized features of the Meike lens.

Image Quality and Performance

Image quality is where the Meike lens shines, with its optimized optical design aimed at achieving high resolution suitable for 8K photography. Its multi-coating significantly improves light transmission and color reproduction, which is vital for achieving vibrant images. The YONGNUO lens, while capable of producing decent images, does not emphasize high-resolution performance to the same degree and may struggle in low-light conditions due to the absence of advanced coatings. Therefore, for photographers prioritizing image fidelity, the Meike lens is likely the superior choice.

Which should you buy?

Choosing between the Meike 85mm F1.8 SE Mark II STM and the YONGNUO YN50mm F1.8 ultimately depends on your specific needs and camera system. The Meike lens, with its advanced features, superior image quality, and optimized design, is well-suited for serious photographers using Sony E Mount cameras who are willing to invest more for enhanced performance. Conversely, the YONGNUO lens offers a budget-friendly option for Canon users who seek versatility and functionality without the need for high-end specifications. If price is a major factor and you use Canon, the YONGNUO lens presents a compelling choice, while the Meike lens is ideal for those focused on premium quality and specialized photography.
